Abstract
The titled compositions are useful binding adhesives, especially, for example, with engineered glass fiber-containing products, and the like. In the A-stage, the compositions are typically exceptionally water soluble and low temperature storage stable. Such compositions can be prepared initially by a procedure in which a resole or the like is copolymerized with free melamine(s) and is conditioned to include acidic stage conditioning. For example, phenol per se, formaldehyde and sodium hydroxide followed by melamine per se and aqueous sulfamic acid solution, with subsequent neutralization, can yield the exceptionally water soluble low temperature storage stable A-stage composition. The C-stage composition is non-punking and can be structurally hard and sound.
